Description

Die Erfindung betrifft ein Rotationsmähwerk mit einem Mähwerkbalken, der an seiner Unterseite Mähwerkzeuge trägt mit den im Oberbegriff des Anspruches 1 angeführten Merkmalen.The invention relates to a rotary mower with a mower bar, which carries mower tools on its underside with the features stated in the preamble of claim 1.

Bei Rotationsmähwerken dieser Gattung ist der Mähwerkbalken von Tragbalken getragen, von denen der äußere Tragbalken am inneren Tragbalken an einer waagrechten Schwenkachse gelagert ist und in unterschiedliche Schwenkstellungen für die Arbeitslagen und die Ruhelage des Hähwerkbalkens verschwenkbar ist. Die Verschwenkung wird mit einem fernbedienbaren, längenveränderlichen Stellmittel bewerkstelligt, das an den beiden Tragbalken an deren Oberseite angelenkt ist.In rotary mowers of this type, the cutter bar is carried by support beams, of which the outer support beam is mounted on the inner support beam on a horizontal pivot axis and can be pivoted into different pivot positions for the working positions and the rest position of the cutter bar. The pivoting is accomplished with a remotely controllable, length-adjustable adjusting means, which is articulated on the two supporting beams on the upper side thereof.

Aus der EP 0 073 360 ist eine solche Maschine bekannt geworden, bei der die Tragbalken in Fahrtrichtung hinter dem Mäh- werkbalken und im Abstand oberhalb von diesem angeordnet sind und die waagrechte Schwenkachse, in Fahrtrichtung gesehen, im Bereich zwischen der Ausgangsprofilwelle eines Winkelgetriebes und der Eingangsprofilwelle eines Verteilergetriebes für den Antrieb der Mähwerkzeuge, vorgesehen ist, um die verbindende Gelenkwelle auch beim Hochschwenken des äußeren Tragbalkens in die Ruhelage des Mähwerkbalkens nicht.. abnehmen zu müssen. Bei zu weitem Hochschwenken des Mähwerkbalkens während der Arbeit, können durch zu starke Abwinke- lungen der Gelenkwelle Beschädigungen an derselben auftreten. Des weiteren ist keine wirksame Entlastungsvorrichtung zur Gewichtsentlastung des Mähwerkbalkens vorgesehen, die aus räumlichen Gründen dem Stellmittel nebengeordnet sein müßte und deren Fehlen ungleichmäßige Belastungen zur Folge hat.From EP 0073360 such a machine is known, in the uh- framing the supporting beams in the direction of travel behind the M and are arranged at a distance above the latter and the horizontal pivot axis, as seen in the direction of travel, in the area between the output profile shaft of a Win kelgetriebes and the input profile shaft of a transfer case for driving the mowing tools, is provided in order not to have to remove the connecting propeller shaft even when swiveling the outer support beam into the rest position of the mower bar. If the mower bar swivels too far up during work, the drive shaft may be bent too sharply. Furthermore, no effective relief device for relieving the weight of the mower bar is provided, which for spatial reasons should have been placed next to the adjusting means and the lack of which results in uneven loads.

Aus der DEOS 29 17 738 ist ferner ein Rotationsmähwerk bekannt geworden, bei dem.das Stellmittel in Form eines Hydraulikzylinders in das Innere des inneren Tragbalkens verlegt ist, dem auch eine Entlastungsvorrichtung bestehend aus mehreren Zugfedern nebengeordnet ist und bei dem der Tragbalken mit einer Konsole für die Lagerung des äußeren Tragbalkens um eine waagrechte Schwenkachse versehen ist.From DEOS 29 17 738 a rotary mower has also become known, in which the adjusting means is laid in the form of a hydraulic cylinder in the interior of the inner support beam, to which a relief device consisting of several tension springs is also arranged and in which the support beam with a bracket for the bearing of the outer support beam is provided around a horizontal swivel axis.

Durch diese Anordnung ist eine erhebliche Anzahl von Bauteilen und ein aufwendiger Aufbau sowohl beim Stellmittel als auch bei der Entlastungsvorrichtung und den Übertragungsteilen für die Schwenkbewegung notwendig. überdies kommt die waagrechte Schwenkachse des Mähwerkbalkens seitlich zu nahe an der Eingangsprofilwelle des Mähwerkantriebes heran, so daß sich ein verringerter Neigungswinkel für den Mähwerkbalken in Arbeitslage ergibt, wodurch das Mähen von sehr steilen Böschungen unmöglich wird oder die Gefahr von Beschädigungen an der Antriebsgelenkwelle in Kauf genommen.As a result of this arrangement, a considerable number of components and a complex structure are necessary both for the actuating means and for the relief device and the transmission parts for the pivoting movement. In addition, the horizontal swivel axis of the mower bar comes too close to the side of the input profile shaft of the mower drive, so that there is a reduced angle of inclination for the mower bar in the working position, which makes mowing very steep slopes impossible or the risk of damage to the drive joint shaft is accepted .

Die Erfindung bezweckt ein Rotationsmähwerk der eingangs beschriebenen Gattung hinsichtlich der Ausgestaltung des Stellmittels und der Entlastungsvorrichtung, sowie deren Anordnung so zu verbessern, daß eine Vereinfachung erreicht wird und die beschriebenen Nachteile weitgehend vermieden werden.The invention aims to improve a rotary mower of the type described in the introduction with regard to the design of the adjusting means and the relief device, as well as their arrangement, so that simplification is achieved and the disadvantages described are largely avoided.

Diese Aufgabe wird an einem Rotationsmähwerk der eingangs beschriebenen Gattung durch die Merkmale des Hauptanspruches gelöst.This object is achieved on a rotary mower of the type described above by the features of the main claim.

Es ergibt sich dadurch eine besonders einfache und günstige Anordnung der Bauteile, insbesonders des Stellmittels, so daß eine höhere Verschwenkung des Mähwerkbalkens zum Mähen sehr steiler Böschungen möglich wird, ohne daß die zulässige Abwinkelung der Antriebsgelenkwelle überschritten wird.This results in a particularly simple and inexpensive arrangement of the components, in particular the actuating means, so that a higher pivoting of the mower bar for mowing very steep slopes is possible without exceeding the permissible angular deflection of the drive cardan shaft.

Die Unteransprüche betreffen günstige Gestaltungsmöglichkeiten der Erfindung im Hinblick auf besonders einfache, zweckmäßige, hinsichtlich der mechanischen Beanspruchung günstige Ausführungen und auch bezüglich der Sicherung der Antriebsgelenkwelle gegen zu starke Abwinkelung während des Betriebes, sowie gegen das ungewollte Herabschwenken des Mähwerkbalkens aus der Ruhelage.The subclaims relate to favorable design options of the invention with regard to particularly simple, expedient designs which are favorable in terms of mechanical stress and also with regard to securing the drive joint shaft against excessive bending during operation, and against the unwanted pivoting down of the mower bar from the rest position.

Eine besonders vorteilhafte Lösung ergibt sich durch die Anbringung eines Zwischenteiles, wodurch eine besonders einfache Anordnung für die Absicherung gegen das Anfahren von Hindernissen ermöglicht wird.A particularly advantageous solution results from the attachment of an intermediate part, which enables a particularly simple arrangement for securing against the approach of obstacles.

Durch die Anbringung eines Schwenkteiles und eines Anschlages sowie einer damit verbundenen Verriegelung ist die Absicherung gegen zu hohes Verschwenken während der Arbeit des Mähwerkes und gegen das Herabschwenken desselben aus der Ruhelage in äußerst einfacher, zweckmäßiger Weise möglich, die auch einer Fernbedienung mittels Seilzug und Rückstellfeder zugänglich ist.By attaching a swivel part and a stop, as well as an associated lock, it is extremely easy and practical to secure against swiveling too much while the mower is working and against swiveling it down from the rest position, which is also accessible by remote control by means of a cable and return spring is.

Ein Ausführungsbeispiel der Erfindung wird an Hand der Zeichnung näher beschrieben.An embodiment of the invention is described in more detail with reference to the drawing.

Das in Fig. 1 dargestellte Rotationsmähwerk besteht aus einem Mähwerkbalken 9, der an seiner Unterseite Mähwerkzeuge 30, 30' an Mähtellern 31,31' an die nach oben Trommeln 32,32' anschließen,trägt und der von einem inneren Tragbalken 1 und einem äußeren Tragbalken 2, an dessen äußerem Ende 12 eine nach unten gerichtete, als Bügel ausgebildete Traglasche 14 befestigt ist, in der eine am Mähwerkbalken 9 befestigte Pendelachse 15 gelagert ist,pendelnd aufgehängt getragen ist. Die Tragbalken 1,2 sind dabei im Abstand oberhalb des Mähwerkbalkens 9 angeordnet, wodurch die Anpassung des Mähwerkbalkens 9 an Bodenunebenheiten durch Pendeln um die Pendelachse 15 in sehr hohem Maße möglich ist.The rotary mower shown in FIG. 1 consists of a mower bar 9, which on its underside connects mower tools 30, 30 'to mower plates 31, 31' to the upward drums 32, 32 ', and which carries an inner support bar 1 and an outer support beam 2, at the outer end 12 of which a downward-looking, bracket-shaped support bracket 14 is fastened, in which a pendulum axis 15 fastened to the cutter bar 9 is supported, is carried in an oscillating manner. The support beams 1, 2 are arranged at a distance above the cutter bar 9, which means that the adaptation of the cutter bar 9 to uneven ground is possible to a very high degree by swinging about the swing axis 15.

Der äußere Tragbalken 2 ist an seinem inneren Ende 13 an einem Zwischenteil 3, an einer waagrechten Schwenkachse 16 mit Lagerlaschen 43,43' schwenkbar gelagert, die das Zwischenteil.3beiderseits umgreifen. Das Zwischenteil 3 ist seinerseits um eine lotrechte Schwenkachse 17 verschwenkbar am inneren Tragbalken 1 gelagert, dessen Lagerlaschen 42 das Zwischenteil 3 übergreifen, wie dies in Fig.2 und 3 wiedergegeben ist. Der Mähwerkbalken 9 mitsamt dem äußeren Tragbalken 2 sind mit ihren Längsachslinien 39,34 quer zur Fahrtrichtung 28 von einer Sicherungsvorrichtung 27 gehalten, die aus einem an der unteren Lagerlasche 42'des inneren Tragbalkens 1 angesetzten Riegelteil 63, einem diesem auf dem Zwischenteil 3 gegenüberliegenden Lagerteil 64 und aus einem Verriegelungsstück 65 besteht, wobei letzteres im einfachsten Fall als Abscherschraube ausgebildet ist, die bei Überlastung z.B.beim Anstoßen des Mähwerkbalkens 9 gegen ein Hindernis, abgetrennt wird und die Schwenkbewegung um die lotrechte Achse 17 freigibt. An Stelle des Abscherbolzens kann das Verriegelungsstück 65 auch aus einer federbelasteten Riegelfalle bekannter Ausführung und Anordnung bestehen (nicht dargestellt).The outer support beam 2 is pivotally mounted at its inner end 13 on an intermediate part 3, on a horizontal pivot axis 16 with bearing brackets 43, 43 ', which engage around the intermediate part 3 on both sides. The intermediate part 3 is in turn mounted on the inner support beam 1 so that it can pivot about a vertical pivot axis 17, the bearing brackets 42 of which overlap the intermediate part 3, as shown in FIGS. 2 and 3. The mower bar 9 together with the outer support beam 2 are held with their longitudinal axis lines 39, 34 transversely to the direction of travel 28 by a securing device 27, which consists of a bolt part 63 attached to the lower bearing bracket 42 ′ of the inner support beam 1, a bearing part opposite this on the intermediate part 3 64 and consists of a locking piece 65, the latter being designed in the simplest case as a shear bolt, which is cut off when overloaded, for example when the mower bar 9 hits an obstacle, and releases the pivoting movement about the vertical axis 17. Instead of the shear pin, the locking piece 65 can also consist of a spring-loaded latch latch of a known design and arrangement (not shown).

Die Tragbalken 1, 2 sind als Vierkantrohre geformt, wobei der äußere Tragbalken 2 von der Lagerung an der waagrechten Schwenkachse 16 bis zu der Traglasche 14 hin schräg gegen die Fahrtrichtung 28 verlaufend angeordnet ist, so daß der Mähwerkbalken 9 zur Fahrtrichtung 28 im Abstand vor dem inneren Tragbalken 1 liegt. Durch diese Anordnung ist es möglich, daß auch die Verbindungslinie 33 zwischen Ausgangsprofilwelle 8 und Eingangsprofilwelle 18 mit der Längsachslinie 39 des Mähwerkbalkens fluchtet.The support beams 1, 2 are shaped as square tubes, the outer support beam 2 from the storage on the horizontal pivot axis 16 to the bracket 14 is arranged obliquely against the direction of travel 28, so that the cutter bar 9 to the direction 28 at a distance in front of the inner support beam 1 is. With this arrangement it is possible that the connecting line 33 between the output profile shaft 8 and input profile shaft 18 is aligned with the longitudinal axis line 39 of the mower bar.

Der innere Tragbalken 1 ist mit Anlenkstellen 4,4', 5 zum Anschluß an das Dreipunkthubwerk eines Schleppers versehen, von denen die obere Anlenkstelle 5 an einer in der Mitte zwischen den unteren Anlenkstellen 4,4' am inneren Tragbal-` ken verschweißten Tragplatte 67 angebracht ist. Die unteren Anlenkstellen 4,4' sind an Trägern 68,68' angeordnet, die mit Laschen 69,69' den inneren Tragbalken 1 oben und unten übergreifen und mit Spannschrauben 41 befestigt, so daß die unteren Anlenkstellen 4,4' je nach den Erfordernissen, versetzt werden können. Bei der oberen Anlenkstelle 5 sind dementsprechend weitere Tragplatten 67',67" neben der mittigen Tragplatte 67 angebracht.The inner support beam 1 is provided with articulation points 4, 4 ', 5 for connection to the three-point linkage of a tractor, of which the upper articulation point 5 is attached to a support plate 67 which is welded in the middle between the lower articulation points 4, 4' on the inner support ball is appropriate. The lower articulation points 4,4 'are arranged on supports 68,68' which overlap the inner supporting beams 1 above and below with tabs 69,69 'and fastened with tensioning screws 41, so that the lower articulation points 4,4' depending on the requirements , can be moved. Accordingly, additional support plates 67 ′, 67 ″ are attached next to the central support plate 67 at the upper articulation point 5.

Im Bereich zwischen den unteren Anlenkstellen 4,4' ist ein Winkelgetriebe 6 an Traglaschen mit dem inneren Tragbalken 1 fest verbunden. Das Winkelgetriebe 6 ist mit einer Eingangsprofilwelle 7,zur Zapfwelle des Schleppers hin gerichtet, zum Anschluß einer Gelenkwelle (nicht dargestellt) und mit einer Ausgangsprofilwelle 8 zum Anschluß einer Gelenkwelle 11, die andernends an der Eingangsprofilwelle 18 eines im Mähwerkbalken 9 angeordneten Verteilergetriebes 19 für den Antrieb der Mähwerkzeuge 30,30', angeschlossen ist.Zusätzlich ist das Winkelgetriebe 6 mit einem Durchtrieb, mit der nach hinten gerichteten weiteren Ausgangsprofilwelle 66 zum Anschluß von Anhängegeräten, wie z.B. einem Selbstladewagen, versehen.In the area between the lower articulation points 4, 4 ′, an angular gear 6 is firmly connected to the inner support beam 1 on support straps. The angular gear 6 is directed towards the PTO shaft of the tractor with an input profile shaft 7, for connecting an articulated shaft (not shown) and with an output profile shaft 8 for connecting an articulated shaft 11, the other end to the input profile shaft 18 of a transfer gear 19 arranged in the mower bar 9 for the Drive of the cutting tools 30, 30 ', is connected. In addition, the bevel gear 6 with a through drive, with the rearward-facing output profile shaft 66 for connecting trailer devices, such as a self loading wagon.

Es ist möglich die Schwenkachsen 16,17 schneidend anzuordnen und im besonderen das Zwischenteil 3 als Kreuzgelenk (nicht dargestellt) auszubilden. In diesem Falle ist es notwendig, daß das Kreuzgelenk mit Fortsätzen versehen ist, die mit der lötrechten Schwenkachse 17 starr verbunden sind, an denen das Pendel 44 und die Sicherungsvorrichtung 27 angebracht sind.The vertical pivot axis 17 can be designed inclined in the direction of travel 28, so that the pivoted to the rear. Mower bar 9 swings forward after being released by an obstacle under its own weight into the working position transverse to the direction of travel 28. For this purpose, the distance between the pivot axes 16, 17 should be as small as possible. It is possible to arrange the pivot axes 16, 17 in a cutting manner and in particular to design the intermediate part 3 as a universal joint (not shown). In this case, it is necessary that the universal joint is provided with extensions which are rigidly connected to the solderable pivot axis 17 to which the pendulum 44 and the securing device 27 are attached.

Zur Verschwenkung des äußeren Tragbalkens 2 mit dem Mähwerkbalken 9 in gegenüber dem inneren Tragbalken 1 unterschiedlich geneigte Arbeitslagen und in eine Ruhelage, in der der Mähwerkbalken 9 eine lotrechte oder noch darüberhinausgehende Lage einnimmt, ist ein fernbedienbares längenveränderliches Stellmittel 20 vorgesehen, das bei der beschriebenen Ausführungsform aus einem einseitig wirkenden hydraulischen Kraftzylinder besteht. Das Stellmittel 20 ist oberhalb der Tragbalken 1 und 2 angeordnet und mit dem äußeren Ende 22 an der Kolbenstange 71 an einem Bolzen 23, der im Lagerteil 24 gelagert ist, angelenkt. Das Lagerteil 24 ist auf dem äußeren Tragbalken 2 an einer Stelle verschweißt, die in Draufsicht in der Mitte zwischen der Längsachslinie 38 des inneren Tragbalkens 1 und der Längsachslinie 39 des Mähwerkbalkens 9 liegt, weil dann die auftretenden Kräfte in besonders günstiger Weise in die Tragbalkenkonstruktion einleitbar sind.To pivot the outer support beam 2 with the mower bar 9 in differently inclined work positions relative to the inner support bar 1 and into a rest position in which the mower bar 9 assumes a perpendicular or even more extensive position, a remotely controllable, length-adjustable adjusting means 20 is provided, which is provided in the embodiment described consists of a single-acting hydraulic power cylinder. The actuating means 20 is arranged above the support beams 1 and 2 and is articulated with the outer end 22 on the piston rod 71 to a bolt 23 which is mounted in the bearing part 24. The bearing part 24 is welded to the outer support beam 2 at a point which, in a plan view, lies in the middle between the longitudinal axis line 38 of the inner support beam 1 and the longitudinal axis line 39 of the mower bar 9 is because then the forces occurring can be introduced into the support beam construction in a particularly favorable manner.

Das innere Ende 21 am Zylinder des Stellmittels 20 ist an einer Anlenkstelle 40 eines Pendels 44 oberhalb des Zwischenteiles 3 angelenkt, das an einer am unteren Ende angeordneten Pendelschwenkachse 45 zwischen den Schwenkachsen 16 und 17 auf dem Zwischenteil 3 gelagert ist.The inner end 21 on the cylinder of the actuating means 20 is articulated at a pivot point 40 of a pendulum 44 above the intermediate part 3, which is mounted on the intermediate part 3 on a pendulum pivot axis 45 arranged at the lower end between the pivot axes 16 and 17.

Das Pendel 44, dessen Pendelschwenkachse 45 parallel zur ' waagrechten Schwenkachse 16 verlaufend, im Abstand 50 von dieser angebracht ist und mit einem Bolzen als Anschlag 47 versehen, der die seitlich außerhalb des Zwischenteiles 3 angeordneten Hebel 49,49' starr verbindet und damit eine steife Hebelanordnung schafft. Am Pendel 44 greift eine Entlastungsvorrichtung 29 mit ihrem ersten Ende 51 an der Anlenkstelle 48 am Pendel 44 an und ist mit dem zweiten Ende 52 an einem Abstützteil 53 des inneren Tragbalkens 1 befestigt und als Zugfeder ausgebildet. Die Entlastung vom Gewicht des Mähwerkes ist durch Wahl der Spannung der Zugfeder möglich, die durch Verstellung der Verschraubung 73 am Abstützteil 53 geschieht.
